Method Detail

all

@SafeVarargs
public final <T> UniJoin.JoinAllStrategy<T> all(Uni<? extends T>... unis)

Join multiple Uni references and emit a list of values, this is a convenience delegate method for all(List).

Type Parameters:

T - the type of the Uni values

Parameters:

unis - the list of Uni to join, must not be null, must not contain any null reference

Returns:

the object to configure the failure management strategy

all

public final <T> UniJoin.JoinAllStrategy<T> all(java.util.List<Uni<? extends T>> unis)

Join multiple Uni references and emit a list of values.

The resulting list of values is in order of the list of Uni. What happens when any of the Uni emits a failure rather than a value is specified by a subsequent call to any of the methods in UniJoin.JoinAllStrategy.

Type Parameters:

T - the type of the Uni values

Parameters:

unis - the list of Uni to join, must not be null, must not contain any null reference

Returns:

the object to configure the failure management strategy

first

@SafeVarargs
public final <T> UniJoin.JoinFirstStrategy<T> first(Uni<? extends T>... unis)

Join multiple Uni and emit the result from the first one to emit a signal, or the first one with a value. This is a convenience delegate method for first(List).

Type Parameters:

T - the type of the Uni values

Parameters:

unis - the list of Uni to join, must not be null, must not contain any null reference

Returns:

the object to configure the failure management strategy

first

public final <T> UniJoin.JoinFirstStrategy<T> first(java.util.List<Uni<? extends T>> unis)

Join multiple Uni and emit the result from the first one to emit a signal, or the first one with a value.

What happens when any of the Uni emits a failure rather than a value is specified by a subsequent call to any of the methods in UniJoin.JoinFirstStrategy.

Type Parameters:

T - the type of the Uni values

Parameters:

unis - the list of Uni to join, must not be null, must not contain any null reference

Returns:

the object to configure the failure management strategy

builder

public <T> UniJoin.Builder<T> builder()

Provide a builder to assemble the Uni references to join.

Type Parameters:

T - the type of the Uni values

Returns:

a new builder
